Języki publikacji
Abstrakty
This article presents the influence of the formation temperature of nonwovens from biodegradable aliphatic polyesters (trade name Bionolle) on their structure and mechanical properties. Nonwovens were produced by spun-bonded technique at a laboratory installation at IBWCh, changing one of the process parameters i.e. the temperature of the polymer. Basic parameters of the polymer were evaluated in order to determine the spun-bonded process condition. Phase transition temperature - glass transition temperature (Tg), -melting point (Tm) and mass flow index (MFI)were assessed. The effect of manufacturing conditions on the properties of the nonwovens obtained was identified on the basis of the analysis of their mechanical parameters, the sorption rate, crystallinity and compost biodegradation rate. It has been shown that 238 °C is the best formation temperature to produce nonwovens with good mechanical properties and at the same time accessible biodegrability.
W artykule przedstawiono badania wpływu temperatury formowania na właściwości mechaniczne i strukturę włóknin otrzymywanych z biodegradowalnego poliestru alifatycznego (nazwa handlowa Bionolle). Włókniny wyprodukowano metodą spun-bonded na instalacji laboratoryjnej IBWCh. Ocenione zostały podstawowe parametry polimeru, które służyły do określenia warunków formowania włóknin, są to między innymi temperatury przemian fazowych: temperatura zeszklenia (Tg), temperatura topnienia (Tm) i masowy indeks płynięcia (MFI). Wpływ warunków wytwarzania na właściwości włóknin został określony na podstawie analizy ich parametrów mechanicznych, szybkości sorpcji, krystaliczności i biodegradacji w środowisku kompostowym. Wykazano, że temperatura wytwarzania włóknin 238 °C pozwala na produkcję włóknin o dobrych właściwościach mechanicznych.
